我在将表单保存到数据库时遇到问题。我尝试过的所有方法都不起作用，我真的不知道还能做什么。
我在 Django 中创建了一个手动表单，保存时绝对没有错误，一切正常，没有任何错误，我什至被重定向到成功页面，但数据库中什么也没有。

我也尝试过使用 {{ form }} 但仍然不起作用。我注意到，我首先在上一页上选择联系人和属性类型，将这两个项目保存到 sessionStorage 中，但关键是整个表单看起来都是空的，就好像我实际上在表单上的任何字段中都没有任何内容一样.
html 文件不完整，因为它太长了，但是其中有很多重要字段，因此您可以弄清楚它的内容。完整的 html 页面可以在这里查看： https://github.com/dolca/crmSystem/blob/main/templates/leads/apartments/add_apartment_lead.html
提前致谢，感谢任何帮助！
